What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeDiffuse villous hyperplasia of the choroid plexus (DVHCP) and choroid plexus papilloma (CPP) are rare benign tumors usually diagnosed as a result of progressive hydrocephalus, especially in childhood. We present the case of a Japanese boy diagnosed with progressive hydrocephalus due to DVHCP.
methodsCase: A 2-year and 3-month-old Japanese boy was found to have delayed motor development (equivalent to 1 year and 2 months old), an enlarged head circumference of 51 cm within + 1.5 standard deviation (S.D.), and incomplete closure of the anterior fontanel. The magnetic resonance imaging (MRI) showed lobular enlargement of the bilateral choroid plexuses extending from the trigone to the body and inferior horn of the lateral ventricle. The endoscopic choroid plexus coagulation surgery was performed to reduce the CSF formation rate.
resultsDVHCP was diagnosed both pathologically and clinically. Postoperatively, the patient progressed without complications, such as cerebrospinal fluid leakage. Although ventricular enlargement persisted, the anterior fontanel recessed, and the expansion of the head circumference stopped.
conclusionFew cases of bilateral DVHCP and CPP have been reported in the literature. We encountered a case in which effective choroid plexus coagulation was performed for hydrocephalus due to DVHCP using less invasive endoscopic technique. It also represented an association between DVHCP and the gain of chromosome 9p.
